GRINDER AND POLISI-IER.

Specification of Letters Patent.

Patented Mar. 15, 191(1).

Application filed. September 14, 1908. Serial No. 452,957.

To all whom it may concern:

Be it known that I, EMILE ADAM, citizen of the Republic of France, andresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Grinders andPolishers, of which the following is a specification.

This invention relates to grinders and polishers and its object is toprovide a simple and cheap device adapted to be applied to sewingmachines or any light machinery used about the house for sharpeningknives, scissors, razors, or other household articles as will be morefully described in the following specification, set forth in the claimsand illustrated in the drawings, where:

Figure 1 is a perspective view of the rear end of a sewing machineshowing the invention applied to the fly-wheel. Fig. 2 is a crosssectional view of the device. Fig. 3 is a side view of same.

The device consists of a ring 5 of rubber or other flexible substancewith a flat periphery 6 and an interior annular groove 7 correspondingwith the run of the fly wheel of the ordinary sewing machine. The flatperiphery is adapted to carry a flexible band 8 having an outer grindingor polishing surface and it may be made of emery cloth, sand paper orleather prepared as a razor strop and which may be fitted on the ringbefore it is applied to the fly wheel or applied after the ring issprung upon the wheel. The flexible nature of the ring readily permitsof its being applied to the wheel and the interior edges of the groovehug the rounded periphery of the run so as to retain it against removaland prevent its slipping.

When the ring is located on the fly wheel and the proper grinding beltapplied the treadle of the sewing machine may be operated and the wheelrun at a high speed to do whatever grinding and polishing that may beneeded about the household, and the belt 8 may be changed when necessaryto provide for different grades of polishing or grinding means as thearticle to be treated may require.

This device forms a very convenient article for household use beingexceedingly cheap and easily applied to the sewing machine and operated.

Vfhen the polishing and grinding belt becomes worn away a new one may beprovided at a very small cost.

In locating the flexible ring in the flywheel the driving belt 9 isremoved from the pulley 10 and the same is done when it is necessary toremove the ring.

It is obvious that the construction of the ring and the belts may bemodified without departing from the essential features above described.

What I claim as new and desire to secure by Letters Patent is:

1. In a grinder and polisher; the combination with the balance wheel ofa sewing machine, of a flexible ring having an interior groove to fitthe wheel and an outer surface adapted to be provided with a grindingand polishing material.

2. In a grinder and polisher, the combination with the balance wheel ofa sewing machine, of a ring of flexible material having an inner grooveto fit the rim of the balance wheel and an outer flat surface andadapted to be sprung on the wheel, and a band with a polishing andgrinding surface adapted to be fitted about the outer edge of the ringwhen it is fitted on the wheel.

Signed at New York in the county of New York and State of New York this3d day of August A. D. 1908.

EMILE ADAM.
